1) The first graph is the graph of f(x) traslated 5 units to the left, then the equation of this graph is: y=(x+5)^2

2) The second graph is the graph of f(x) traslated 5 units upward, then the equation of this graph is: y=x^2+5

3) The third graph is the graph of f(x) traslated 5 units downward, then the equation of this graph is: y=x^2-5

4) The fourth graph is the graph of f(x) traslated 5 units to the right, then the equation of this graph is: y=(x-5)^2

A sequence consists of the positive odd integers. What is the sum of the first 12 terms of the sequence?
Volgvan

Answer:

A

Step-by-step explanation:

The sequence of positive odd numbers is

1, 3, 5, 7, ......

This is an arithmetic sequence with common difference d

d = 3 - 1 = 5 - 3 = 7 - 5 = 2

The sum to n terms of an arithmetic sequence is

S_{n} = \frac{n}{2}[2a + (n - 1)d ]

where a is the first term

here a = 1, d = 2, n = 12, hence

S_{12} = \frac{12}{2}[1 + (11 × 2) ]

                         = 6 [ 2 + (11 × 2) ]

                        = 6 × 24 = 144 → A
